The Correct Option is A

Solution and Explanation

Step 1: The question asks which malaria-related measure is not a true epidemiological indicator of disease burden.
Step 2: ABER, the Annual Blood Examination Rate, measures the proportion of the population whose blood is examined for malaria. It reflects how well the programme is performing its surveillance, not how much disease exists.
Step 3: Therefore ABER is an indicator of operational efficiency of the Malaria Control Programme rather than an epidemiological indicator.
Step 4: By contrast, the annual parasite index and the annual falciparum incidence are genuine epidemiological indicators of malaria burden, so the odd one out is ABER.
